No way to delete history of the base shape?

[cooki]

i got a character with its target blendshapes mad already. The thing is the model is put in the wrong place and i need to move it to the right place. before binding, i'd really like to keep the history clean....but i know if I kill the blendshape, freezetransform the model and delete its history.....i can't make a new blendshape that would work! the model would fly to its target shapes.

anyone knows a way to keep the history clean and make the blendshape work after moving the model?

thanks,

Identtify a vertex that does not move in relation to the base and perform a 2 point snap to the bases location freeze delete hostory... Continue with the next shape.

In general the rule of thumb however is thet motly you never want to freeze anything if you do you ususaly want to do it in the real beginning of the process cor some special reason.

secondly you realy dont need to worry about history on blends. Since disconnecting the histry trees of all but the parent shape will act as a prifying filter for dowstraem nodes.

Joojaa, thanks for the reply.

um...not sure if I get ur point. do you mean to snap the vertices of each target shape to the base one? The sentence is kind of confusing...

The thing is, i'm helping someone with his character...and he already made the blendshapes with wrong-placed base model. so, I'm trying to fix the mistake ><

it's not about the history of the blends...it's the history of the model i'm going to bind. If I freezetransform it without cleaning the history...there would be a transform node.

do this.

1) identtify a vertex or a cv that corresponds bin bot the blend and the traget. one that is NOT transsfromed in relation to the base (there should be one of those)

if not then the pivpts could snap to eachother. Asuming the pivot is still intact.

2)select the point then select the corresponding point in the blend target (do this one by one).

3) perform Modify->Snap Align Objects->Point to Point

4) freeze, repeat for next shape.

in other words:

1)If You already have good-working targets, then omit this and just make sure they have same location as base obj and proceed with next step. Otherwise "turn on" every single blendshape and duplicate base object, so You'll re-gain targets for each blend.

2) Select all of them (base too), move to correct place, snap their pivots collectively to one point (e.g. origin), and delete history, freeze transforms.

3) Rename targets if necessary. Blend.

NOTE: Delete blend targets at final phase of rigging only, and keep one file with them exported.
